I believe that their company will definitely carry out training on "personal leave" during the training. As long as they put you on duty. They will certainly approve your leave. If there is a shortage of people, their company will allocate manpower and deduct your money at most.

You have been looking for brands of cosmetics. And even if the makeup brand calls you for an interview, it can't be a weekend call. You can't rest at work on weekends. So you can go for an interview on your day off. If the interview is successful, it will take 3-5 days of training. You can take personal leave. You can learn about the salary during the training. Then make a comparison for yourself. When you know what you are doing, you can choose one.
